segfault installing -current in QEMU

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

Trying to install -current (201109151700Z or so) in QEMU fails loading
"instfs.tgz" from the CD image:

I saw there was some problems with booting -current in QEMU not too
long ago.  That seems to not be a problem for me.  I've only recently
started experimenting with the QEMU sparc emulator, though.  I was
able to install 5.1_STABLE without any trouble.
